@PeroK ,@vanhees71, it seems this is the case of jump discontinuity And still our solution manages to give average value, how cool is this?

Wow insight is good and satisfying, is their a mathematical theory behind this?, Some kind of theorem regarding integration ambiguity of this kind?

Yep i had written r'instead of r'^2 and dr instead of dr', now its been edited

First i tried proving Newton shell theorem directly for r=R and solved the integral as above but still got the wrong solution. Here i tried using general case: Here r' is the distance of a small ring from the point particle of mass m So my doubt is when we take r=R and then evaluate this...

Thank you everyone, her theorem really inspired me, really remarkable, i am a big fan of feynman and from now emmy noether is one of a kind, i think i have to make "list of favourites".:smile:

So what i undrstood is that yes her theorem can prove if there is a symmetry of such kind then there will be a conservation of particular kind, since maths is so complex i could understand this much only.

How do we know that such a such type of symmetry will give you such a such type of conservation law Can we simillarly prove that if there is translation symmetry then momentum is conserved and if there is rotational symmetry then angular momentum is conserved.

I don't know much about classical physics(such as lagrangian function), but as i was reading conservation of energy, i came to this theorem and it tells that if a system is symmetrical in certain transformations(such as translation, rotation etc) then it will have a corresponding law of...

What are antiparticles and what do they do? How do we know that they do exist? Could you explain these in layman's term,because I don't know much about quantum mechanics.

Sir why i am not able to make a private conversation with you on physics forum

Could you explain it with a physics example(not mathematically) Just like i could say as mass increases obviously its hard for a body to accelarate and we could relate this with real life very easily but I am not able to relate inverse relation of force and displacement when work is constant...

So they are inversely proportional, give me examples, i can not imagine their inverse relation, as force increases,displacement also increases how it will decrease, but direction is also important

From Newton's 2nd law F = ma and a = F/m(acceleration and mass are inversely related when force is constant) But in w = F.d , F =w/d(but d and F are not inversly related just as above) I think there's something wrong in my question, please point it to me or please answer it.

Wonderfull explanation, just replace v^2 by v Thank you so much, for this explanation

I know that, this is not the magnitude of acceleration, it will be root of the sum of the square of components in both tangential and radical direction, but in v=rω its the total magnitude of the velocity and in a= rα its not the magnitude of total acceleration, its just the magnitude along the...
